Great advice Nic!
Reviewing your own products is a great way to get started. It's good practice for you and encouraging your readers to leave some feedback about the posts will help prep you even more for when you move on to company reviews.
I love going to a local baby and toy boutiques to speak with a salesperson about their favorite products and check items out in the store. There's nothing out of your pocket and it's a great way to be hands on with products. If the shop has a website, you can give them some or all of the links which helps support a local biz as well!
